Hi,

I got today my new TL-WPA8630P KIT and quickly installed it. Big surprise: the theoretical data rate is in the interval [75Mbps,125Mbps]  (info from tpPLC and the Web Configuration tool).

The real speed is actually way lower: average 19.9 Mbits/sec. I used iperf3 for that. 

Setup: iperf3 running in server mode on one of my local severs:

[SERVER_X]  <-- eth_1Gbps --> [Archer C7 (AC1750)] <-- eth_1Gbps --> [TL-PA8010P 2.0] <~~ power_line ~~> [TL-WPA8630P 2.0] <-- eth_1Gbps --> [client_PC] - running iperf in client mode.

There is a RE450 as well in the network, but I would not count it as it is just a WiFi extender and doesn't play any role in the ethernet + powerline equation.

Well, knowing that the powerline is not very long (really generously 25m), I thought to make a test more closely one from another.

So I went nearby my rooter,  and I plugged the  [TL-WPA8630P 2.0] in the power socket provided by  [TL-PA8010P 2.0] which is plugged itself into a wall socket - literally one on top of another. I've got data rates in the interval of [350Mbps,450Mbps] ( tpPLC).

Well that was very curious - closer than that they would not get. Well, maybe they have some internal filter or something - I thought - so I plugged them in 2 adjacent power plugs mounted on the wall: data rates in the interval of [350Mbps,450Mbps] ( tpPLC).

The theoretical advertised speed is 1300Mbps via powerline and with the interference from the powerline, I was ready for 400Mbps near my desktop PC plug, not 10cm from each other.

Is there anything I can do to test them or to improve the quality?

Please note:

- The above are LAN bitrates NOT Internet and the Archer C7 router is NOT provided by the ISP (basically the ISP is not involved at all in all of this - I don't care about the internet at this point);

- The tests were done on different power plugs (extremely close, very close, some room, different rooms) but always wall mounted without any power strips involved (basically no surge protector);

- No major appliances were running apart form the TV;

- The server I've used supports way higher transfer speeds: Tested from the same spot via WiFi provided by the extender TP-Link RE450. The server is used generally as a NAS.

I bought the  TL-WPA8630P KIT to improve my existing Archer_C7+RE450 combo, which is giving me 25Mbps in 2.4Ghz and about 55MBps in 5Ghz.

Acctually, the situation got worse than before. The only place where this stuff is giving any acceptable bitrates is in the most useless place possible - 1m form the router.

Is there anything I can do? Is there any environment where I can test it and get at least 1Gbps (out of 1300Mbps advertised)?

Best regards
